GF Piping Systems has introduced a family of NSF lead-free brass valves designed to handle high loads and strong flow rates in commercial grade and light industrial water distribution applications. Valve styles include pressure reducing, thermostatic balancing, and thermostatic mixing.

ʺWe are pleased to add these five high-quality brass valves to our traditionally all thermoplastic valve product line,” says Ralph Abdelhak, Product Manager of GF Piping Systems. “The three valve styles provide different solutions for commercial water systems in high-rise buildings, multi-family dwellings, hospitals, hotels, sports facilities, universities, dormitories, and industrial buildings.”

First in the family are the compact, direct-acting Pressure Reducing Valves Type 1319 and 1339.  The two PRV valves feature excellent control characteristics, even at low flow rates. This patented design, which offers a 416 stainless steel floating seat and modular construction, allows for a more compact size. The EPDM diaphragm and seals provide superior resistance to strong and oxidizing disinfectants such as chlorine. Available in sizes 1/2” to 2-1/2”, these valves handle hot water temperatures up to 158°F, inlet pressures up to 357 psi, and comply with NSF 61 and NSF 372.  Other outstanding characteristics include a choice of two pressure control ranges, easy cleaning, and downstream pressure gauge ports standard on both sides.

Next in the family is the new Type 6320 Thermostatic Balancing Valve. The balancing valve regulates the flow rate in hot water (up to 158°F) circulating systems by continuously sensing the return water temperature with an integrated thermostat, ensuring consistent system temperature. This low maintenance 3/4” valve features field adjustable temperature set points, overheat protection, and simple regulator operation. Regulating the flow rate to meet temperature set points allows for a shorter heat up phase after temperature drop, increasing energy savings.

Last in the new family are the Thermostatic Mixing Valves Type 3409 and 3419, which accurately deliver tempered water to hot water distribution systems.  Mountable in any position, the two mixing valves are ASSE 1017 compliant when installed with a check valve or combination check/stop on the hot and cold water inlets.  The unique, integrated circulation inlet saves installation labor and materials. Other performance attributes include scald protection, energy savings, capability to operate without an external power supply, and field adjustable outlet temperature ranges.
